In each question, a. number series is given. Only one number is wrong which doesn’t fit in the series. Find out the wrong number
26 29 22 25 18 23 14

Options

A. 18
B. 25
C. 29
D. 23

Answer

To find the wrong number in the series: 26, 29, 22, 25, 18, 23, 14, we will analyze the pattern of the series step by step.

### Step 1: Identify the pattern
Let's look at the differences between consecutive numbers in the series:
- 29 - 26 = 3
- 22 - 29 = -7
- 25 - 22 = 3
- 18 - 25 = -7
- 23 - 18 = 5
- 14 - 23 = -9

### Step 2: Analyze the differences
From the differences calculated:
- The pattern seems to alternate between adding 3 and subtracting a number.
- The first part of the pattern is: +3, -7, +3, -7.
- However, the last two differences do not follow this pattern.

### Step 3: Check the last two numbers
The last two differences are:
- 18 to 23 is +5 (which breaks the previous pattern)
- 23 to 14 is -9

### Step 4: Identify the inconsistency
The inconsistency arises with the number 23. If we were to follow the established pattern of alternating +3 and -7, the number following 18 should have been 21 (18 + 3), not 23.

### Conclusion
Thus, the wrong number in the series is **23**.
